AGETYLENE-GAS GENERATOR.

SPECIFICATION forming part of Letters Patent No. 663,169, dated December 4, 1900.

Application filed Apri1l8,l900. Serial No. 31 99- (N modem Kenosha, in the county of Kenosha and State of Wisconsin,have invented certain new and useful Improvements in Acetylene-Generators, of which the following is a specification.

This invention relates to improvements in acetylene-generators of that type in which the generating liquid is supplied to the carbid in a substantially Continuous flow regulated or in part regulatedandcontrolled by. the pressure of gas generated, and refers more specifically to an improved liquid-distributing mechanism for properly regulating and distributing the flow to insure a uniform and efficient generation. V

The object of the invention is to provide a construction in which the internal or backpressure of the generated gas acts most efficiently to regulate the control or inflow of liquid, to so construct and arrange the sup ply-ducts that the supply of liquid will be substantially unaffected by the heat of generation, thereby preventing the vaporization of the liquid before it reaches the body of carbid and enabling the generation to be properly localized, and in general to providea simple, efficient, and inexpensive construction of the character described.

To the above ends the invention consists in the matters hereinafter described, and more particularly pointed out in the appended claims, and Will be readily understood from the following description,reference being had to the accompanying drawing, wherein the single figure represents an ordinary velocipede-lamp equipped with my invention, the generator of the lamp and the principal feature of the liquid-distributing mechanism being shown in axial section.

Referring to the drawing, 1 designates the generating-chamber, which so far as the present invention is concerned may be of any usual type adapted to contain a body of car-' bid, (indicated at 2.)

3 designates a liquid-supply reservoir elevated above the generating-chamber-in the present instance by being mounted upon the rear end of the headlight or flame chamber 4- and 5 designates a supply pipe or duct leading from the lower part of the liquid-reservoir through and into the upper portion of the generating-chamber and communicating with a distributing-chamber, (designated as a whole by 6.) The supply-pipe 5 is desirably provided with a controlling-cock 7, for con venience of access located outside of the generating-chamber,whereby the flow of liquid to the generating-chamber maybe cut off at will, and may also be partially regulated by restricting tle flow through the said pipe.

Describing now more particularly the peculiar construction and arrangement of the distributing-chamber, which constitutes the essential feature of novelty'of the present invention, said device, as shown, comprises an elongated receptacle, preferably made tapering or conical from a point intermediate of its length upwardly and downwardly toward each end and circular in cross-section, the lower end terminating in a conical point 8, while the upper end 9 communicates with the supply-pipe 5. The distributing-chamberis completely closed, except for the inlet at its point of communication with the supplypipe and an outlet-opening 10, arranged to extend through its upper conical wall portion a short distance below its juncture with the supply- P 1 6- ll designates a coil of pipe, hereinafter termed the pressure-coil, located entirely within the distributingchamber and arranged vertically therein, the upper end 12 of said pipe communicating with the outletpassage 10 of the distributing-chamber, while the lower end 13 of the coil is arranged to communicate with the interior of the distributing-chamber, near the lower end, thereof. The main body of the coil consists of horizontally-disposed turns and in the preferred construction shown herein is so shaped as a Whole as to conform approximately to the internal formation of the distributing-chamher, but is made sufiicientlysmaller than the latter in all its dimensions, so that it extends freely within the space of the distributing-chamber and is completely surrounded and jacketed by the liquid when in operation.

Inthe operation of the device water admitted fromthe reservoir through the supplypipe enters and fills the distributing- IOO - out over the conical outer surface of the distributing-chamber and is by the latter conveyed to the body of carbid, within which it extends. By reason of the peculiar construction of the exterior of the distributing-chamber the liquid will be distributed more or less uniformly over its surface and conveyed to those portions of the charge which rest in immediate contact with its sides. As soon as the pressure in the generating-chamber exceeds the pressure of the hydraulic head, due to the elevated reservoir, the pressure will force back the liquid in the pressurecoil, and by reason of the fact thatany given portion of the pressure-coil, except the extreme lower inlet end thereof, is but'slightly inclined with reference to a horizontal plane intersecting said portion a relatively large surface area of the liquid contained in said coil will be exposed to the internal pressure of the gas, and the regulation will therefore be extremely sensitive. At the same time the length of the passage through said coil, by reason of its tortuous arrangement, will be relatively great, so that although the liquid will be promptly driven back sufficiently to arrest the escape thereof as soon as the internal pressure exceeds the hydraulic pressure, yet the liquid will not be driven back far enough to permit the gas to escape into the distributing-chamber through the lower end of the coil, and thus permitted to escape into the reservoir except under unusual conditions.

Another feature of importance incident to the construction described is thatthe liquid in the pressure-coil is jacketed from the internal heat of the generator, so that it reaches the exterior of the distributing-chamber at a relatively low temperature and is therefore not vaporized before it has time to flow over the surface of the latter down into the body of carbid, and it will be further noted that the walls of the distributingchamber will also be kept relatively cool by means of the liquid within said chamber.

It will be obvious from the foregoing description that the details of construction may be modified to a certain extent Without departing from the spirit of the invention, and

communicating at its upper portion with the liquid-supply duct, a discharge-outlet located at the upper part of said distributing-chamher and a. pressure-coil arranged within the :ber, as and for the purposes described.

2. In an acetylene-generator, the combination with a generating-chamber, a liquid-reservoir elevated with reference to said generating-chamber and a supply=duct leading from the reservoir and extending into the generating-chamber, of means for controlling and distributing theliquid, comprising a distrib utin'g-chamber' provided with a conical lower end portion arranged to extend into the body of carbid and communicating at its upper end with the supply-pipe leading from the reservoir, a discharge-outlet located in the upper part of said distributing-chamber and arranged to discharge the liquid upon the conical exterior thereof, and a pressure-coil arranged within the distributing-chamber and communicating at its upper end with the discharge outl'et, the upper portion of said coil consisting of approximately horizontally-disposed coils and the" lower inta'king end being arranged to communicate with the interior of the distributing-chamber near the bottom thereof, as and for the purposes described.

3. In an acetylene-generator, the combination with a generating-chamber, a liquid-reservoirelevated with reference to said generating-chamber and a supply-duct leading from the reservoir and extending into the generating-chamber, of means for controlling and distributing the liquid, comprising a distrib tiring-chamber provided with a conical lower end portion arranged to extend intothe body of cal-bid and communicating at its upper end with-the supply-pipe leading from the reservoir, a discharge-outlet located in the upper part of said distributing-chamber and arranged to discharge the liquid upon the conical exterior thereof, and a pressure-coil arranged within the distributing-chamber and communicating at its upper'en'd with the discharge-outlet thereof, said coil comprising a plurality of horizontally-disposed turns and being formed to conform as a whole'approximately' to the intern'al'shape' of the distrib- ;utin"g cha1nber, but of smaller size in all its dimensions than the corresponding dimensions of the distributing-chamber, so as to be insulated by the liquid of the distributingcha'mber from the heat of the generatingchambera'nd arranged to communicate at its lower end with the lower portion of the distributing-c'hamber, substantially as and for the purposes described;
